Circuit breakers are important mechanisms used to prevent excess short-term volatility and to ensure price continuity. This article presents the results of an international survey on the design and application of circuit breakers on trading venues worldwide. The majority (86%) of the responding trading venues apply circuit breakers and thereby aim to ensure investor protection and increase market integrity and stability. On cash markets, market-wide trading halts and volatility interruptions are the most prevalent types of circuit breakers (72%). On derivatives markets, most exchanges coordinate their circuit breaker with their cash market (40%), followed by marketwide trading halts (20%) and volatility interruptions (13%). Most circuit breakers do not differentiate between upward and downward market movements. There is also support for greater coordination of circuit breakers across venues, and a few exchanges (32%) already coordinate their circuit breakers with other venues.

Between April and June 2016, the Chair of e-Finance and the World Federation of Exchanges (WFE) conducted an international survey on market safeguards (so-called circuit breakers). In total, 44 of the 72 contacted trading venues answered the questionnaire resulting in a response rate of about 61%. Among the participants are well-known exchanges such as Deutsche Boerse, New York Stock Exchange, Nasdaq and the Chicago Mercantile Exchange. The results show that 38 of 44 exchanges already implemented circuit breakers. Compared to an earlier WFE-survey from 2008, the proportion of exchanges which use circuit breakers increased from 60% to 86%. By analyzing the different types of circuit breakers, it can be observed that market-wide trading interruptions (complete suspension of trading) and volatility interruptions (interruption of continuous trading by a call auction) are most widely used. Exchanges were also asked about the coordination of circuit breakers among several trading venues. In this context, 69% of the answering exchanges support a stronger coordination, however, only 32% already coordinate their circuit breakers.
